Photogrammetric Estimates of Mass and Body Condition of Leopard Seals in the Antarctic Using an Unmanned Aerial System from 2013-01-01 to 2014-03-31 (NCEI Accession 0168214)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2017-11-29T00:00:00.000+00:00
We aerially surveyed leopard seals of known body size and mass to test the precision and accuracy of photogrammetry from a small Unmanned Aerial System (UAS). Flights were conducted in January and February of 2013 and 2014 and 50 photogrammetric samples were obtained from 15 unrestrained seals. Photogrammetric measurements from a single, vertical image obtained using UAS provide a noninvasive approach for estimating the mass and body condition of pinnipeds that may be widely applicable.
